I don’t think the music industry cares about college, grades, your 33 ACT score or any of that stuff. They care about talent and stage presence. If you want to be a singer, build your talent, put your 10,000 hours of practice into that and front a band. Perform. Audition for everything.
Would you consider going into something like music production or sound editing or something technical like that? Then you could work in the music industry even though you aren’t the best musician yet…
